[Feature Request] hydra.utils.get_object method

[Jasha10]

🚀 Feature Request

The hydra.utils module exposes get_class and get_method functions that can be used to look up callable objects:

>>> from hydra.utils import get_method
>>> get_method("torch.tensor")
<built-in method tensor of type object at 0x7fdbd8ff1760>

To resolve the given string, these methods use the same backend as hydra.utils.instantiate.

The get_class and get_method functions error if the given dotpath does not point to a callable:

>>> get_method("torch.double")
...
ValueError: Located non-callable of type 'dtype' while loading 'torch.double'

I think it would be useful to expose a get_object function in hydra.utils that does not give an error in this case. This would allow users to leverage Hydra's dotpath-lookup mechanism to discover arbitrary objects (rather than just callable ones).
